The Minecraft Beta option isn't in my insider previews, I've had it before but its not...

If the game is slated for May, and the beta comes out in April, that means there will be no time to work on the game after the beta.

As I've stated before it isn't really a beta, it's just a preview.

Hi Viprer,

To my knowledge, I am not enrolled in the insider preview program lol.

Thats the program for beta testing system updates, isn't it?

I had this problem before and the one fix was this:

Are anyone of yous using the Xbox Insider Program and if you are, did you install the beta version of minecraft from that? If you did, opt out of the beta and uninstall minecraft, reinstall and it should be fine.

I believe you may be enrolled in Minecraft Beta in the Xbox Insider for PC and you need to un-enroll. Do not rejoin the Beta if you do not want the Beta.
